Alex needs an extra touch

John walks out of the pool, focused squarely on Alex. Still carrying the cum covered sister, Maria, he lays her on a lounger. Then walks promptly inside toward Alex, who squeaks and ducks there head back.

Soon enough, John lumbered in front of the bathroom door, his wet chest still glistening from a mixture of pool water sweat.

“Go away John. I saw you fucking her.”, they tried desperately to sound sincere. Though he was pretty sure her hand was certainly between her legs still, from the muffled panting. “Always the bridesmaid…” they quietly lamented.

John thought quickly, Of course, the little sister was insecure. She was smaller all over. But …that could change. My cum is now delicious and eating it makes them grow taller, bustier and, like, stronger!

John went for the door, it was locked. He pressed his strength further into the handle, it whined in defiance. A slow shift handle then tore free from the door. The door flung quickly away, into the room.

Alex was sitting there on the tub edge clutching their frantic chest. Her eyes went wide as the door flung wide and was replaced with naked John rippling head to toe. His semi solid log swinging like a pendulum. It had just been roughly impaling her sister, though the moans said she enjoyed every moment. Now she was eye to eye with the monster. He cleared the distance in the room quickly, though she was transfixed now.

Up. And again it rose to its full mast, a veiny and proud organ. Now throwing inches away from her face. Her mental defenses have long since crumbled. The aroma of the post sex breeder was overpowering in the small room.

She latched onto the head, sloppily kissing over the head. Her hand desperately tries to wrap the beast, but successfully covers only mostly. Now slowly pumping the beast, his pre now reaching her tongue. Had he seen her eyes that moment, he’d have seen the instant dilation.

“Hnnngh John fucking use me, give me it. Goooood it tastes so good”, now frantically licking and sucking him up. He groaned as his hand fell on her head, feeling her try to please him, hell pleaded for it.

Then his grip tightening on her head as hip began to push. The needy girl opens and soon the bulbous head is being pushed in. Luckily they can always take his size. Slowly but sure more of his length as deep throat face fucking her. A chick he’s known for years and had only dreamt of doing shit like this. Now he’s bulging out her throat with his meat. Alex having her eyes rolled back, just drooling as they were bounced.

His balls tighten and release. He decides to pull when clearly filled her up with a distended stomach and the cum still leaking from her nose. His tool yet finished with painting her face and chest with a final thick contemptuous volley as he pulled away. A continuous groan comes from Alex as she falls back into the tub.

He could see it working. Slowly the sister grew up hitting nice 6’ tall, slowly inflating to tone then athletic all over. The faint line of the four pack slowly budging into six. The churning of her chest as her breast expanded, her cute nipples remained small as they rest blew up. Growing well passed DD size, they still rode high from the decent pecs beneath to hold them.

The new improved Alex found her feet, as her fingers absently licked the cum. Now closer to his height the growing sexy that was Alex now was eying him like a piece of meat.
